Is typical Mastodon etiquette to repost everything you like rather than "liking" it?

Just perusing, I consistently see 0 likes on posts that have several reposts.

@grantmc I sometimes like instead of boosting in order not to fill people's feeds with cat pictures!
@grantmc Mainly I boost if I think other people should see something, like if I just want to acknowledge my appreciation, or (more rarely) both if something’s a real home run.
